No, the parent element in a nuclear reaction is not always radioactive. While many parent isotopes are indeed radioactive and decay into stable or unstable daughter isotopes, there are also stable isotopes that can undergo nuclear reactions without being radioactive themselves. For example, stable isotopes can be involved in nuclear reactions such as neutron capture or fusion, but they do not decay over time like radioactive isotopes.
What else can I help you with?
Is the parent isotope always radioactive In a nuclear equation?
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.
All nuclear reactions due to nuclear transmutation?
Nuclear reactions may or may not involve nuclear transmutation. We need to split hairs here to arrive at the correct answer, and the answer involves the definition of the word transmutation. We sometimes think of transmutation as the changing of one element to another. Fission and fusion reactions do this, and many kinds of radioactive decay also convert one element into another. But there are some kinds of nuclear reactions that do not change an atom from one element to another, but instead change it from one isotope of a given element into another isotope of that element. There are a number of examples of this, and one is where isotopes of a given element absorb a neutron and become another isotope of that element. A given nucleus incorporates the neutron into its nuclear arrangement and the next heavier isotope of that element is created. If a "strict" definition of transmutation is used where it means a nuclear reaction that changes one element into another, then no, this does not always happen as illustrated above with the example of neutron absorption. If a more general interpretation of the term is used where we say that the nucleus transmutes meaning changes configuration, then yes, nuclear reactions involve nuclear transmutation.
A redox Reaction is always a single displacement reaction but a single displacement reaction isn't always a redox reaction true or false?
False. A redox reaction involves the transfer of electrons and changes in oxidation states, while a single displacement reaction is a specific type of reaction where an element displaces another in a compound. Not all single displacement reactions involve a change in oxidation states, so they aren't always redox reactions. Thus, the statement is incorrect.
Is moderation of neutrons always used to slow nuclear fission?
No, moderation of neutrons is not always used to slow nuclear fission. In some types of nuclear reactors, such as fast breeder reactors, fast neutrons are intentionally not moderated to slow down the fission process. These reactors operate using fast neutrons to sustain a chain reaction. However, in most commercial nuclear reactors, moderation of neutrons is employed to slow down the fission process and maintain a controlled chain reaction.
Is catalyst a compound?
No, a catalyst is not a compound itself. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged chemically at the end of the reaction.
Is the parent isotope always radioactive In a nuclear equation?
No, the parent in the nuclear equation is not always radioactive. For example, the following reaction shows a neutron capture by 23Na, which is not radioactive. 1123Na + 01n --> 1124Na where 01n is a neutron.
What the element is halogen?
Astatine, the always radioactive one.
What element is the rare halogen?
Astatine, the always radioactive one.
Why do we put in lead chamber for radioactive element?
Radioactive elements always emit hazardous radiations.Lead metal absorbs these radiations .Hence we put any radioactive element in a lead chamber.
Does nuclear radiation go away?
No, it doesn't.Wrong, it does. There are 2 types of nuclear radiation: prompt & decay.Prompt nuclear radiation occurs for a period of time while the reaction that generates it is happening. Examples are the flash of neutrons, light, x-rays, etc. when a nuclear bomb explodes as well as the sustained neutron flux as a nuclear reactor is in operation. When the reaction stops, prompt nuclear radiation goes away.Decay nuclear radiation occurs as radioactive isotopes decay to different isotopes. As the decay happens (which is a probabilistic process) the radioactive isotope is consumed. This follows an exponential function with one half of the current amount of the radioactive isotope consumed in each period of time called a halflife. While there will always be a tiny residue of the original radioactive isotope, for practical purposes it is considered to be negligible after 5 halflives have passed. When 5 halflives of the radioactive isotope decaying have passed, decay nuclear radiation is considered to have gone away for practical purposes.
Which element is always presented in a combustion reaction?
oxygen
Does a radioactive element become stable after its mass number become less than 82?
Not always -- Hydrogen-3 is radioactive, for example.
What is a plutonium?
A radioactive element with several isotopes that always has 94 protons within its nucleus.
What decays first duriing radioactive decay?
No, radioactive decay is not a chemical reaction. Radioactive decay is a type of change in the nucleus of an atom that results from instability in that nucleus. And that is a nuclear reaction rather than a chemical one.
Why radioactive decay is always first order reaction?
This is because only one isotope decay.
How is it that radioactive decay has always warmed the earth from the inside and nuclear fusion has always warmed the earth from the outside?
That's because of where each of these processes occur. There is no nuclear fusion inside of Earth. There is probably a small amount of radioactive decay in the Sun, but the power produced by it is insignificant, compared to the huge amount of power produced by nuclear fusion.
Why are protons and neutrons always equal in number?
Because they are both in the nucleus and if they weren't the element would be radioactive.
